Pediatrician: Child psychologists recommend that mothers of one-year olds not only name objects in the immediate environment, but that they include the color of the object, when applicable. For instance, if a mother hands her child a red ball, she should say, “This is a red ball.” Nonetheless, even if mothers began to name the color, instead of simply saying, “This is a ball,” no real benefit will be conferred to the child, because studies have shown that children under 18-months old do not grasp the notion of color.
The pediatrician’s argument is most vulnerable to which of the following?The pediatrician argues that naming colors gives no benefit because children under 18 months do not understand color.
The flaw is that the child might still benefit in another way, even if the child does not yet understand
color itself.
(A) Infants who hear words embedded in sentences that have each part of speech present tend to speak sooner than those infants who do not.
This is correct. If richer sentences help infants speak sooner, then saying “This is a red ball” may benefit the child even if the child does not yet understand the concept of color.
(B) Children usually benefit from having toys in their environments.
This is irrelevant. The issue is whether naming colors provides a benefit, not whether toys are useful.
(C) The range at which children utter their first sentence typically ranges from 15-months to 30-months.
This does not weaken the argument. It gives general information about speech timing, but it does not show that naming colors helps children.
(D) Children under the age of three tend to be confused when parents use adult level vocabulary.
This does not weaken the pediatrician’s argument. If anything, it could support caution about using more complex language.
(E) Psychologists have conducted studies showing that most children under the age of 30 months often utter the names of colors even when that color is not present in their environments.
This is not enough. Saying color words does not show that children under 18 months understand color or benefit from hearing color labels.
